摘要:

资源环境承载能力研究是现阶段中国国土空间规划和乡村振兴规划中重要的基础工作,而以往的承载能力研究多是面向大区域尺度,专门针对村镇建设的承载能力评估比较少。本文在总结前人研究的基础上,以自然资源部最新公布的国土空间规划“双评价”技术指南为基准,探讨了县域尺度面向村镇建设的资源环境承载能力评价方法,选取的案例区为地处江南丘陵地区的江西省永丰县。通过永丰县村镇建设特点及其资源环境限制因素的初步评判,建立了以土地、地质灾害、生态为主要限制因子的种植业和村镇建设不适宜区判定的指标体系,划分了以行政村为基础单元的村镇建设适宜类型,测算了高开发强度和平均开发强度两种情景下的全县人口合理规模。研究结果表明:①永丰县种植业和村镇建设不适宜区面积分别为1779.77 km2和1838.68 km2,剔除重叠面积后为1838.94 km2,占全县面积的67.81%。②按照各村不适宜区面积、现状人口、村镇建设的情况,全县216个行政村可被分为生态保护重点村、种植业发展重点村、中心集聚重点村和其他村4大类。③当地高开发强度和平均开发强度情景下,全县耕地种植业可承载的最大人口规模分别为135.38万和140.10万人。④按照人均建设用地100、140和200 m2测算,高开发强度情景下,全县村镇建设用地可承载的人口数量分别为84.05万、60.04万和42.03万人;平均开发强度情景下可承载的人口规模分别为54.61万、39.01万和27.31万人。本文研究结果可为现行“双评价”技术指南的应用与完善提供案例支撑,也可为永丰县实施乡村振兴和村镇规划提供参考依据。

Abstract:

The research of resources and environmental carrying capacity is an important basic work in China’s national land use planning and rural revitalization planning. Current research on resources and environmental carrying capacity remains at large regional scale, and the evaluation of carrying capacity for villages and towns is relatively uncommon. Based on a summary of previous research, this study explored the evaluation method of resources and environmental carrying capacity for villages and towns at the county scale on the basis of the “dual evaluation” technical guideline of the National Land and Spatial Planning published by the Ministry of Natural Resources. Yongfeng County of Jiangxi Province, which is located in the hilly area south of the Yangtze River, with a total population of 44×104 in 2017, was taken as an example. Based on the preliminary evaluation of the characteristics of the village and town development in Yongfeng County and the resources and environmental constraints, the index system for determining the unsuitable areas for cropping and village and town development with land, geological hazards, and ecology as the main limiting factors was established, and administrative villages were classified. Appropriate types of village and town development for village units and optimal population size of the county were determined under two scenarios of high development intensity and average development intensity. The results of the study show that the areas unsuitable for cropping and village and town development in Yongfeng County were 1797.77 km2and 1838.68 km2, respectively, which is 1838.94 km2 excluding the overlapping area, accounting for 67.81% of the county area. According to the unsuitable area, current population, and village and town development level, the 216 administrative villages in the county can be divided into four major categories: ecological protection key villages, cropping development key villages, central key villages, and other villages. Under the scenarios of local high development intensity and average development intensity, the largest population that the county’s arable land and planting industry can support will be 135.38×104 and 140.10×104, respectively. Assuming 100 m2, 140 m2, and 200 m2 per capita construction land, under the high-intensity development scenario, the number of population that can be supported by villages and towns in the county will be 84.05×104, 60.04×104, and 42.03×104 respectively; under the average development intensity scenario, the population size will be 54.61×104, 39.01×104, and 27.31×104 respectively. The results of this research can provide a case for the current “dual evaluation” technical guideline, and provide a reference for the implementation of rural revitalization and village and town planning in Yongfeng County.
